Degree of protection
The degrees of protection according to IEC60529 apply to various articles and provide information on protection against the intrusion of water and solids such as dust.
Degree of protection

IP40 (725)IP40
Protects against contact with tools, wires and other similar objects of Ø > 1 mm and against the intrusion of foreign bodies of Ø > 1 mm. Does not protect against water.

IP67 (947)IP67
Fully protects against touch and against the intrusion of dust. Protects against water intrusion in temporary immersion (depth: 1 m; duration: 30 minutes).

IP67 when unplugged as well (2)IP67 when unplugged as well
Fully protects against touch and against the intrusion of dust. Protects against water intrusion in temporary immersion (depth: 1 m; duration: 30 minutes).

Version
The choice of version allows the definition of certain technical specifications – for example the type of cable outlet or the size.
Version

Adapter (2)Adapter
Connecting element to each side of which a connector can be attached. This enables the realisation of, for example, control cabinet lead-throughs or a transition from the M8 to the M12 locking system.

Distributor (2)Distributor
In distributors, an input current or signal is distributed over multiple outlets according to a particular wiring logic. The locking system/termination for the input may differ from that for the outlet.

EMC
Electromagnetic compatibility (EMC) means that a connector is shielded or shieldable. This is required when it is necessary to protect the signals or data conducted by the connector, as well as to protect external devices, from disturbance due to electromagnetic effects.
